Abstract

Objective: To examine the effectiveness of nutritional education based on the health action process approach (HAPA) on pregnancy outcomes among malnourished pregnant mothers utilizing nutritional support.

Methods: In a randomized controlled trial, 234 malnourished pregnant women under nutritional support from the fourth month of pregnancy participated. Participants were randomly allocated in study groups by the balance block randomization method. Data were collected using a socio-demographic and pregnancy outcomes checklist as well as self-devised questionnaire assessing the constructs of the HAPA model before and three months after the educational intervention. The framework of the educational intervention was based on the constructs of the HAPA and included three one-hour training sessions through lectures, group discussions, ‘question and answer’ sessions, and the use of educational tools. Data were analyzed using analysis of covariance (ANCOVA) and SPSS software.

Results: Pregnancy outcomes including optimal weight gain during pregnancy (p = 0.47), neonate’s birth weight (p = 0.58), gestational age at delivery (p = 0.83), type of delivery (p = 0.48) gestational anemia (p = 0.22), diabetes (p = 0.59) and hypertension (p = 0.29) were not significantly different in the intervention and control groups. The results showed that the educational intervention produced a significant increase in the total score (24 points) in the intervention group. Improvement of scores in the intervention group compared to the control was observed in all of the model constructs except outcome expectation (0.68 decrease). The educational intervention in the present study had a large measure of effect in total (SMD: 2.69, partial eta2: 0.664).

Conclusion: A nutritional education intervention based on the HAPA model for malnourished pregnant women increased behavioral intention and planning for action to have better nutritional behavior. However, the intervention did not change the pregnancy outcomes significantly.

Practice implications: Nutritional education based on the HAPA model can be used to improve nutritional behaviors of malnourished pregnant women.
